Abstract: SECURITY HINGE     Abstract of Disclosure A security hinge is disclosed which includes a pair of leaves, having respectively, at least a pair of spaced end knuckles and at least one immediate knuckle disposed there-between.  Each knuckle includes a central axial bore, the bores being aligned co-axially.  A pair of pins are provided, each pin having a head portion disposed in an end knuckle bore for rotation in unison therewith and a body portion thereof disposed within an intermediate knuckle bore to main-tain the leaves in assembly and permit relative rotation there-between the pin and intermediate knuckle.  Stop means, are pro-vided interiorly of the bores, against which the heads of the respective pins abut, thus preventing the pins from being driven completely through the end knuckle bores in the axially inward direction.  Since the pins are recessed within the bores, and one prevents the other from being forced out of the bores in the axially outward direction, unauthorized disassembly of the hinge is precluded.  The hinge may be provided with con-tinuous passage means into which one or more electrical con-ductors are engaged, so that said conductor is substantially concealed, the hinge giving the outward appearance of a con-ventional, load bearing hinge.

Granted: 1981-12-22
Abstract: VARIABLE ANGLE ELECTRONIC HALFTONE SCREENING   ABSTRACT OF THE DISCLOSURE         An electronic signal representing the density of a scanned image is electronically halftoned by combining the pictorial signal with a rectangular array of halftone screen values to form an electronic halftone image.  The electronic screen function represented by the array of halftone screen values is rotated at variable angles to the original electronic image by defining a repetitive rectangular matrix representative of any predetermined halftone cell approximating a parallelogram and incorporating a shifting parameter for the repetitive rectangular matrix.  An efficient, high speed, partial-dot halftoning technique is performed by indexing the screen function rectangular array, under the supervision of the shifting parameter, against the scanned image values for a realtime serial combination of the functional values.

Abstract: ABSTRACT OF THE DISCLOSURE     A plastic container has a neck formed with a substantially horizontal flat top.  On the inside of the neck proceeding down-wardly there is a substantially vertical first sealing surface, then a top groove, then a very smooth second sealing surface of less diameter than the first sealing surface terminating in a lower groove and then a vertical stretch which merges into a breast which widens out to the full size of the container.  On the outside of the neck proceeding downward from the flat top is a first vertical surface terminating in a horizontal inwardly extending shoulder below the elevation of the top groove, then an indented second vertical surface of lesser diameter than the first vertical surface and then an external bead having an outward-downward slanted top surface and a bottom horizontal inward-directed second shoulder at about the level of the lower groove, then a third vertical surface at about the level of the vertical stretch.  The container is blow-molded or injection molded and, except at the top of the neck, where it is thicker, has a substantially uniform wall thickness.  However, the second sealing surface has an "injection finish" obtained by use of a blow pin in the mold.  The cap is an improvement on that shown in U. S. Patent No, 3,338,446.  The upper and lower internal beads (which seat under the first and second shoulder of the neck) are interrupted in a plurality of gaps, permitting stretching of the cap to seat on the neck.  The top disc has a peripheral flange which may be gripped to lift the cap when the bottom of the skirt is torn off. However the flange is flexible, bending to prevent prying off the cap when the skirt is intact.

Abstract: ABSTRACT         A light reflector for a light is disclosed which may be formed by progressive dies to form all electrical contacts from a coil or sheet of the electrically conductive metal.  After for-mation of the contacts and buss work the last stage of the pro-gressive die automatically inserts the buss work on the plastic reflector which is secured by tinnerman type locks formed by the progressive die or by heat staking.  The reflector supports a printed circuit card which contains the circuit and switching means.  The end result is the elimination of any wiring from the PC Card to the battery and fluorescent tube contacts.  The angu-lar mounds direct any misaligned battery contacts to the proper contact area.  Trusses formed on their reflector are aligned to support the battery pick-up contacts to avoid contact deflection, and assure proper contact orientation.  The switch protrudes from a preformed window in the lantern case after assembly.
